not only are you just rushing through content and only finishing it once. your neglecting many gear pieces. first off you might want to farm up a set of darklight armor and umm.... upgrade your lvl 9 ring. secondly you can farm up garuda/titan weapons and work on AF+1 and relic +1 THEN you guys can make some honest attempts at coil of bahamut (bring 23 friends along with some maxed gear). as far as crying about end-game content your gear is just screaming fresh 50 so dont complain yet.
